A method for removeably fitting a flow control regulator (5) into a plumbing outlet (2) has a cartridge design fitted directly into the outlet and secured by a screw thread. The cartridge locates into the bottom of the outlet bore and has an inlet aperture matching the outlet aperture of the plumbing fitting. This eliminates trapped spaces where debris and impurities could collect. An alternate design has a press fit sleeve inserted into the plumbing outlet to form a grip into which the cartridge is fitted. The cartridge is fitted and removed using conventional tools.

Description

Plumbing outlet mechanism {PLUMBING OUTLET FITTING}

The present invention relates to a sanitary outflow armature having a liquid guide open into an outlet of a piping fitting, wherein the piping functional unit is configured in the form of a cartridge in the outlet region. The cross section of the opening of the liquid guide portion corresponds to the insertion cartridge in the open region of the outlet mechanism, and the insertion cartridge is from the opening side into the outlet mechanism. It can be inserted and detachably secured to the outlet mechanism.

It is provided in the outlet region of the apparatus sanitation facility drain (sanitary outflow armature) to the pipe functional units, as well as is used to generate a weak non-spray-jet (non-spraying jet). Known injection regulators can be inserted into a sleeve-shaped outlet nozzle, which can be screwed to the tip of the outlet mechanism.

However, sleeve-shaped outlet nozzles secured to the outlet mechanism require expensive machining on the outlet mechanism and, moreover, limit structural clearance in the design of such outlet mechanism. In addition, outlet nozzles, which are generally fabricated as chromed, separate metal collars, result in significantly higher additional costs.

In particular, for high quality instruments that must meet high aesthetic demands, the instrument and associated nozzles are costly so that the smoothest transition possible between the instrument and the nozzles is achieved and the diameters match with each other without color deviation and gaps. It must be polished, polished, subsequent chrome plating or painting.
The prescribed gap between the nozzle and the instrument fixed to the outlet instrument tip under the use of conventional nozzles not only confuses the visual appearance of such an instrument, but also has a drawback from a hygienic point of view due to the collection of dirt. .
From CH-A-380 042, a pipe outlet mechanism of the above-mentioned type is known, in which the opening region is provided with an injection controller in the form of an insert cartridge. The opening in the open area of the pipe outlet mechanism fits snugly into the insert cartridge so that the cartridge can be inserted into the outlet at the open side in a removable manner. At the open side of the insert cartridge, the circumferential wall has a hexagonal shape, in which a socket wrench can be arranged for attachment and screwing. The injection cartridge-type injection controller may be inserted into the outlet stop to the insertion stop, and the insertion stop and the adjacent tip surface of the insertion cartridge are sealed around the shaft in a ring shape.
The outlet mechanism known from CH-A-380 042 makes additional chrome-plated metal colors and expensive connections with them unnecessary. However, in order to create an insertion stop required for axial sealing inside the tubing outlet tube, a relatively thick tube to be milled out in the opening area is required, or a corresponding annular flange is required. There is a need to add later, and thus additionally significant manufacturing costs.

Thus, there is a need to invent a sanitary drainage device that can be used with a spray regulator or other piping functional unit or can be used without the limitation of structural clearance, nevertheless distinguished by its relatively low manufacturing cost. do.

In the pipe outlet mechanism of the type mentioned above, the solution according to the present invention to this problem is in particular a radially sealed in a circumferential form with the insertion cartridge leaning against the intermediate holder or against the inner circumferential wall of the outlet, and / or intermediate The holder abuts against the inner circumferential wall of the outlet and is radially sealed circumferentially.

The functional unit, in the form of an insert cartridge, can be inserted into the outlet from the opening side and fixed in such a way that it can be removed there. To receive this insert cartridge, the inside diameter of the liquid guide device of the outlet mechanism is adapted to fit the insert cartridge at least in the opening area of the outlet mechanism. Thus, the outlet nozzles and the extra considerable cost therefor can be saved; until now. Such nozzles have accounted for an excessively high proportion of the total cost of the outlet mechanism. The fabrication of the sanitary drainage mechanism is greatly simplified since such mandatory outlet nozzle installation can be omitted and also such an exit nozzle does not have to be manufactured together for color matching with the outlet mechanism. However, the costs associated with the fabrication of the outlet mechanism according to the invention also include the fact that the insert cartridge is radially sealed in a circumferential form against the intermediate holder or against the inner circumferential wall of the outlet mechanism, and / or the intermediate holder is inside the outlet mechanism. Significant savings are achieved by sealing radially circumferentially against the circumferential wall. Due to this radial seal, insertion stops or similar sealing flanges, which are required for axial sealing, can be omitted, which, if not omitted, will result in a correspondingly thicker tube body mold at a significant manufacturing cost. It may have to be produced or produced later by inserting an annular flange and made in the opening area of the outlet mechanism. Because the nozzle can be omitted. The use of conventional nozzles generally avoids gaps that generally exist between the nozzle and the outlet mechanism, and have the effect of confusing vision and hindering desirable sanitary purposes. The piping functional unit is fixed so that it can be removed from the outlet mechanism of the sanitary drainage reinforcement, and thus can be easily separated and even removed by a user unskilled for service tasks such as, for example, dirt removal or lime removal. Omission of the outlet nozzle also increases the structural simplicity in the design of the outlet mechanism, so that, for example, it is also possible to use a colored outlet mechanism without the additional cost of producing a special nozzle with a corresponding color.

It is useful if the insertion cartridge is located in the outlet mechanism with at least a major portion extending mainly in the longitudinal axis, preferably with the whole extending in the longitudinal axis. If the insertion cartridge is positioned in the outlet mechanism while extending in the longitudinal direction as a whole, it can be mounted in the outlet mechanism so that it can be hidden, i.e. substantially invisible from the outside, and safe for operation. For example, it may be separated using a crown key or opening wrench, or some other removal tool.

The insert cartridge can be secured immediately in the outlet mechanism without further modification. In another particular embodiment according to the invention, the insert cartridge is secured in the outlet mechanism, preferably using an intermediate holder in the form of a sleeve.

Here, it is possible for the intermediate holder, which can be inserted into the outlet mechanism from the opening side, to be inserted into the outlet mechanism in a manner that can be removed or in a non-removable manner.

It is useful if the intermediate holder is secured in the outlet mechanism, using an adhesive connection, a clamp connection, a locking connection, and / or a screw connection, and / or via a press, clutch, wedging. Here it is advantageous if the intermediate holder is leaning against the inner circumferential wall of the outlet mechanism and preferably sealed in a direction surrounding the entire circumferential wall. Outlet mechanisms, for example, using additional sealing members such as O-rings or flat sealing members, sealing members formed in intermediate holders, or using connecting means such as, for example, bonding means used for bonding intermediate holders. In this case, the sealing of the intermediate holder may occur.

It is advantageous if the insert cartridge is secured in the outlet mechanism or intermediate holder using a clamp connection, a locking connection, or a screw connection. Thus, for example, the insertion cartridge can be fixed in the outlet mechanism or the intermediate holder by a screwed connection with one or more threaded threads, or by a snap connection; This kind of removable connection allows for quick and simple assembly and disassembly of the required functional units.

In a preferred specific embodiment according to the invention, at least one annular sealing member, preferably for sealing between the insert cartridge and / or intermediate holder on the one hand and between the insert cartridge and / or the outlet mechanism on the other hand, is preferred. At least one O-ring sealing member is provided.

According to a further improved embodiment according to the invention, the insert cartridge or the intermediate holder has an external thread that can be screwed into the internal threading in the outlet mechanism, the external thread and the internal thread of the insert cartridge and / or Or when the intermediate holders are screwed together, on the one hand the threads are fixed to each other at the relative position of the outlet mechanism and on the other hand the insert cartridge and / or an O-ring or similar ring seal therein. The intermediate holder, which is provided on the outer circumference of the insert cartridge or the intermediate holder, is dimensioned and positioned in such a way that it does not yet make frictional contact with the outlet mechanism. Through the position of the annular sealing member, the annular sealing member quickly seals the insertion cartridge in the instrument housing, where obvious advantages can be used during assembly and disassembly; During assembly, the threads are noticeably larger in finding the thread, because the annular seal does not compress rapidly until the thread is already found. Compression of the annular seal creates a large amount of friction, otherwise the assembly will feel much more difficult. During disassembly. The condition of the selected annular sealing member has the advantage that the insertion cartridge rotates from the outlet mechanism and the screwed connection with the aid of the insertion and removal tool. As long as the annular seal is still compressed, axial movement is forced through the threads. The threads will not engage until the annular sealing member leaves the outlet mechanism in the axial direction. This has a decisive advantage: the functional unit, which is constructed as a hidden insert cartridge and, if necessary, engages the intermediate holder, is completely removed from the outlet mechanism by rotational movement without the need for additional axial retraction or hydraulic pressure support due to frictional effects. There is an advantage that it can be removed.

However, it is also possible for the at least one circumferential sealing member to be formed as a body on the insert cartridge; Here, the insert cartridge in the sealing area can be made not only as a multi-component injection molded part, but also in particular as a single component injection molded part.

It is particularly advantageous according to the invention that the insert cartridge and / or the intermediate holder are thus at least one circumferential between the insert cartridge and / or the intermediate holder on the one hand and the outlet mechanism on the other hand, thus ensuring separation protection. It is connected to the sealing member and one body. The sealing member in the form of a body provided in the insertion cartridge and / or the intermediate holder is on the one hand between the insertion cartridge and / or the intermediate holder on the other hand and the outlet mechanism on the other hand, such as liquid flowing through the outlet mechanism. Or prevent leakage.
It may be advantageous if the leading region at the water flow inlet surface of the insert cartridge and / or intermediate holder is made as a sealing profile. Such a design can be manufactured with a relatively wide tip without undue limitation of the inner and outer cross sections. This results in a relatively complex sealing member shape which can be used very successfully immediately following a relatively wide tip in the insert cartridge and / or in the intermediate holder.
In the realization of the sealing member form, it is useful for the sealing member form to have at least one surface sealing member and / or at least one lip seal. The form of such a sealing member is counterstop of the outlet mechanism if the sealing member form contacts a corresponding stop and thus exerts a linear and / or surface pressure on the sealing member form. ) Can form an effective seal.
In order to prevent excessive deformation of the sealing member shape, it is useful if the insert cartridge and / or the inner holder have the insertion stop at the water flow inlet side and restrict the deformation of the sealing member shape at its use position. Otherwise, the sealing member shape may be damaged or excessively deformed, which may cause leakage in the area between the insert cartridge and / or the inner holder and the outlet mechanism and the water flow may be slowed down.
In the formation of the sealing member form, it is advantageous if the sealing member form has at least one sealing member with a sealing profile base made as an insertion stop. The sealing member form may be located here on the upper limit surface of the sealing member form base. The insertion stop, for example, may serve to limit the screw depth if the insertion cartridge or the intermediate holder is fixed to the outlet mechanism via the screw connection. If it is possible to screw by hand without the use of a tool, the insertion stop can convey the solid feeling of the screw connection, so that contact with the corresponding stop against the outlet mechanism can be felt through the insertion stop.
To make the inner diameter of the insert cartridge and / or intermediate holder as large as possible available, or to avoid unnecessarily narrowing the inner diameter. It is useful if the sealing member shape and, if necessary, its insertion stop function together with the tip area of the outlet mechanism restricting the inner diameter, while at the same time the tip area functions as a corresponding stop for the insert cartridge and / or the intermediate holder.
Here, it is particularly useful if the insertion stop is located near the seal member in the radial direction for the function of the insertion stop. In this way, the insertion stop can be precisely subjected to a force that can damage the sealing member shape. Moreover, in this way, a space saving position in the form of an insertion stop or in the form of a sealing member can be achieved in the inside diameter of the injection regulator.
If the sealing member is provided to form at least one ring-shaped circumferential sealing cover (sealing lip) it can be prepared by simple and effective sealing of the sealing member forms. Such a sealing cover may be made in an elastic and flexible manner so that it can be adapted to the counterstop in the outlet mechanism during fixing the insert cartridge and / or the intermediate holder, or while the deformation is so difficult that the sealing cover is fixed. The sealing cover may be formed in such a way that it is sealed only through surface pressure by the corresponding stop of the outlet mechanism. These two possibilities can be combined with multiple sealing covers in various ways.
Particularly advantageous sealing member form fabrication allows the sealing member form to have at least two annular sealing covers which in turn become effective as the insertion pressure acting on the injection regulator increases. This step-by-step fabrication of the sealing member form can have the effect that the neighboring sealing cover in the form of a sealing member becomes effective even if one sealing cover fails. Furthermore, by fixing the components screwed to the outlet mechanism, i.e., the insert cartridge and / or the intermediate holder, the effect of the insertion pressure is manifested so that at least a further sealing in the form of a sealing member can also be effective.
In the further manufacture of the annular circumferential seal, which in turn is effective, these seals have different heights. In this way, if the insert cartridge and / or intermediate holder are used for a long time. As the components screwed to the outlet mechanism are tightened tightly, the sealing effect can be maintained for a long time. If the highest sealing cover is already damaged or worn to some extent and becomes inflexible, the next higher sealing cover will be more taut to achieve a sealing effect again. Furthermore, a small non-uniformity of the corresponding stop of the outlet mechanism can be compensated for. It may be advantageous here if the sealing cover has a stepwise height, and if the highest sealing cover forms an innermost or outermost seal in the form of a sealing member.

It is possible for components of the insert cartridge and / or intermediate holder to be sealed to be fabricated as a multi-component injection-molded part, which components are flexible and / or in at least one sealing area. Or it can be made of elastic material. However, for simple recycling of the materials constituting the insert cartridge and / or intermediate holder, the sealing member and its components, connected by one body, of the insert cartridge and / or intermediate holder are of the same material, preferably food-safe ( It is useful to be made of food-safe materials. This simplifies manufacturing costs and allows the tooling costs for the injection molding tools needed to be kept relatively inexpensive.

A preferred development according to the invention is that the piping function unit is made as a spray regulator.

In Figures 1 and 2 the sanitary drainage reinforcement is shown as two different embodiments 1 and 2. The outlet mechanisms 1 and 2 have a liquid guide 3 which is open into the outlet 4. In the outlet 4 region, the pipe function unit 5 is equipped to function as a spray regulator. The functional unit 5, which functions as an injection controller, is manufactured as an insertion cartridge, and is provided with at least an injection classification device and an injection control device inside the insertion cartridge.
1 and 2, the insert cartridge 5 can be inserted into the outlet 4 from the openings of the outlet mechanisms 1, 2, and is removably fixed therein, the insert cartridge 5 being here in the longitudinal direction throughout and completely at the outlet 4. It can be seen that it is elongated and positioned virtually invisible.
Insertion cartridge 5 of outlet mechanism 1 shown in FIG. 1 can be immediately positioned into outlet 4. The insert cartridge 5 of the outlet mechanism 2 shown in FIG. 2 can be secured immediately in the outlet 4 by means of a sleeve- or cup-shaped intermediate holder 6.
The intermediate holder 6 may be fixedly or nonremovably fixed in the outlet 4. The intermediate holder 6 in the outlet 4 can be fixed here using, for example, a clamp connection, a locking connection, and / or a screw connection. If the intermediate holder 6 is adhered to the outlet 4, the adhesive used can be used as a sealing means for sealing the intermediate holder 6 against the inner circumferential wall of the outlet 4 at the same time. In such an embodiment the intermediate holder 6 is fixed so that it cannot be removed from the outlet mechanism 2, and the intermediate holder 6 can be easily positioned into the outlet mechanism 2 by the manufacture of the part, and consequently the front of the outlet mechanism 2 therein. It will remain for its lifetime. The insert cartridge 5 is also secured to the intermediate holder 6 of the outlet mechanism 2 so that it cannot be removed so that the user can easily remove it from the outlet mechanism 2 when needed, for example when performing service operations for debris removal or descaling operations. Can be removed
The outlet mechanism 1,2 shown here can be manufactured at a relatively low cost without significant cost. As shown in FIG. 2, the special equipment of the outlet mechanism intended to hold the intermediate holder 6 may be omitted. Additional cost is saved by omitting the outlet nozzles prepared in advance.
In FIGS. 1 and 2, the machining of the outlet mechanism in the outlet mechanism area intended to receive the piping functional unit is for example a simple outletless hole, or an outletless hole with a simple coupling geometry, for example. For example, it can be achieved by constructing a groove (groove). If the coupling structure provided between the functional unit 5 and the outlet mechanism 1,2 is correspondingly manufactured, the standardization of the outlet mechanism can be omitted entirely.
For example, the intermediate holder 6 can be fixed in the outlet 4 by pressing, gluing, snapping, clutching, or wedging, for example an O-ring. Alternatively, the intermediate holder 6 may be sealed in the outlet 4 by using an additional seal such as a flat sealing member, by using a seal sprayed onto the intermediate holder 6, or by means of the above-mentioned bonding means such as an adhesive used for bonding. have.
1 and 2, the insert cartridge 5 can be removably secured in the outlet mechanism 1,2 using a screw connection. Numerous variations are possible to secure the insertion cartridge, such as, for example, single or multithreaded threaded connections, snap connections, or another removable connection to simplify assembly disassembly.
In the outlet mechanism shown in FIG. 1, the insert cartridge 5 is fixed directly in the opening area of the outlet 4 without intervention of the intermediate holder 6. The outlet mechanism 1 shown in FIG. 1 has an internal thread in the outlet 4 region for this purpose, in which the insert cartridge 5 is screwed from the outside. Here, the insertion cartridge 5, which is configured as an insertion jet regulator, can be screwed tightly, for example using a crown key that engages the outline of the insertion cartridge between longitudinal webs (thin metal plate). have. The assembly and disassembly of the insert cartridge 5 intended for the outlet mechanism 1,2 may also be standardized or used for example on the lower tip surface of the insert cartridge 5 for screwing the insert cartridge into the outlet mechanism 1,2. This can be done using a specified tool.
3 The sanitary drainage reinforcement 2 is shown in the outlet 4 area of the liquid guide 3. In the outlet 4 region, the piping function unit is provided in the outlet cartridge 4 in the form of an insertion cartridge 5 and fixed in the outlet 4 via the sleeve-shaped intermediate holder 6. Insertion cartridge 5 may be located in the intermediate holder 6 from the water flow inlet surface of the intermediate holder 6 to the holding projection (7). The intermediate holder 6 has an external thread 8 in its circumferential edge region at the water flow discharge surface. The external thread 8 has the intermediate holder 6 and the entire insertion cartridge 5 positioned therein extending in the longitudinal axis direction. In a manner that is fully positioned at outlet 4, it can be screwed into an internal thread that is complementary at outlet 4.

On the side facing away from the flow direction of the external thread 8, an annular seal 11 fixed to an annular groove 10 is provided on the circumference of the intermediate holder, so that the intermediate holder 6 and the outlet mechanism 1 Provides a seal in the radial direction between the inner circumference of the. Here, the insert cartridge 5 is configured from the injection regulator 12 on the water flow discharge surface, the jet regulator 12 is connected to the sieve in a direction opposite to the water flow direction, preferably in a removable manner It is connected to the water flow inlet as well as with a flow regulator 13.

On the water flow inlet surface of the inner holder 6 an additional sieve attachment 15 is provided so that it can extend beyond the inner liquid guide 13 having a relatively large cross-sectional area of the outlet mechanism 2. The attachment body 15 is connected to the intermediate holder 6 in a removable manner and for this purpose has a peripheral locking projection 16 at its circumferential edge, the circumferential locking projection 16 of the intermediate holder 6. Engage with annular grooves on the inner circumference at the water flow inlet. An annular seal 17 for sealing in the axial direction is provided between the attachment 15 and the end face on the water flow inlet face of the injection regulator 12 of the insert cartridge 5; The injection regulator 12 is secured between the attachment body 15 with the annular flange 18 and the fixing projection 7. Functional units of standard construction, for example injection regulators, water flow regulators, backflow preventers, and / or attachments may be inserted in the intermediate holder 6.
Figure 4 shows the sanitary drainage reinforcement 1, the piping functional unit of the insert cartridge 5 type in the outlet end of the sanitary drainage reinforcement can also be inserted without an intermediate holder. For this purpose. The insert cartridge 5 has a multi-part cartridge housing 19, which is made of two parts here, the outer thread of the housing part 20 at the water discharge side. threading) 21. The insertion cartridge 5 may be screwed with the outer thread 21 on an inner thread located on the inner circumference of the liquid guide portion 3 provided at the discharging end of the outlet mechanism 1. In addition, the housing portion 20 is provided with an annular seal 11 on the outer surface of the thread 21 in the direction facing away from the water flow direction; The annular seal is located in an annular groove over the outer circumference of the cartridge housing 19.

Insertion cartridge 5 in FIG. 4 is also located within outlet 4 in its entirety extending essentially completely longitudinally. The insert cartridge 5 also has a water flow discharge surface injection controller 12 having an injection separator 22 and an accessory injection control device 23. The injection regulator 12 is connected to the water flow regulator 13 at the water flow discharge surface, and the attachment body 14 is connected in the direction opposite to the water flow from the water flow regulator 13.

Due to the multipart construction of the cartridge housing 19, the insert cartridge 5 of FIG. 4 has a modular construction. The housing part 20 allows the insert cartridge to be installed in the outlet mechanism 1 even without the intermediate holder 6 and the nozzle, while an additional housing part of the water flow outlet, which is not optionally provided with external thread mounts (shown in FIG. 4). Is used to install an insertion cartridge in a standard nozzle, for example.

3 and 4 show that the insertion cartridge is installed in the outlet mechanism manufactured as a molded part, whereas in the longitudinal right half section of FIGS. 3 and 4 these insertion cartridges are metal tubes. It can be installed in the outlet mechanism manufactured on the open surface.

3 and 4, the intermediate holder 6 of FIG. 3 and the insertion cartridge 5 of FIG. 4 have a tip surface at the water flow discharge surface, which is composed of protrusions and recesses 24 and is outlined. and, the contour line (contouring) are produced as for the insertion tool is formed in a complementary tool engagement surface (tool engagement surface), where coins can be used (standard coin piece) as an insertion tool.

In contrast, FIG. 5 shows the outlet mechanism 1 as compared to the outlet mechanism shown in FIG. 4, wherein an insertion cartridge 5 is arranged in the outlet mechanism 1, and one of the insertion cartridges 5 is arranged in the outlet mechanism 1. Another insert cartridge 5 'of identical construction is prepared for replacement. From Fig. 5, the end surface of the water discharge surface of each of the insert cartridges 5 and 5 'has a contouring consisting of protrusions and recesses 24 at its end edges. to there be seen, the vent mechanism 1 of the recess 24 of the inserted cartridge 5 fixed to the functions as a tool engagement surface (tool engagement surface) with respect to the protrusion (projection) 25 of the other insertion cartridges 5 'and, in this case be used as an insertion tool, And vice versa. The protrusions 25 and the recesses 24 of the water discharge end faces of the insertion cartridges 5 and 5 'constitute a crown-shaped lower edge in each case, and the crown-shaped teeth are assembled or disassembled relative to each other. mating piece).

In Figure 5 the complete insert cartridge 5 'is used for the replacement of the insert cartridge 5 arranged in the outlet mechanism 1, but also on the side only an additional intermediate holder 6, or an additional cartridge of the insert cartridge which is not provided for other purposes. Only the housing can be used, for example to screw in the insert cartridge 5 located in the outlet mechanism or to screw in the intermediate holder 6. For this purpose, the manufacturer of the outlet mechanism can provide the outlet mechanism with only an additional intermediate holder or an additional cartridge housing intended for use as an insertion tool. The above does not require the outlet mechanism manufacturer to supply a second functional unit that can be installed in the outlet mechanism, and additional intermediate holders or cartridge cartridge housings in which a relatively large number of mechanisms are manufactured and used provide a very economical alternative. It has the advantage of representing.
The outlet mechanism 2 is shown in FIG. 6, wherein an insert cartridge 5 can be arranged in the outlet mechanism 2 using the intermediate holder 6 compared to the insert cartridge shown in FIG. 3. An annular seal 11 fabricated as an O-ring is provided on the intermediate holder 6 shown in FIG. 3, while a seal 30 on the insert cartridge 5 shown in FIG. 6 is instead of one body. It is composed on the water flow inlet in a way that makes The sealing member (seal), which is configured in the flow of water entering the front end region of the cartridge housing as a single body 30 as well as the circumferential exterior of the insertion stop portion 32 parallel to, located in the sealing cover is configured as a sealing member type having a sealing lid 31 . In the position of use of the insert cartridge 5, the insertion stop 32 limits the deformation of the seal 30 and its sealing member form. The sealing member form with a sealing cover 31 and its insertion stop 32 acts in conjunction with the annular projection 33 located around the inner circumference of the outlet part at its use position to define a clear outlet cross section of the outlet mechanism 2. . The cartridge housing of the insert cartridge 5 forms a body with a seal 30, which can be manufactured as a single component or multicomponent injection molded part. For simple recycling of the materials used in the manufacture of the insert cartridge and its intermediate holder, the cartridge housing and the seal 30 formed thereon are nevertheless made of the same material, preferably a food-safe material. Is useful. In this way, manufacturing costs can be reduced and tool costs for the injection molding tool that may be needed can be kept relatively inexpensive.
As can be seen by comparing FIGS. 3 and 6, since the additional attachment 15 shown in FIG. 3 can be omitted as a snap ring at the annular seals 11, 17 and the water flow inlet, FIG. 6. The insert cartridge 5 shown in Fig. 1 is remarkably easy to manufacture, which greatly simplifies assembly manufacturing.
The longitudinal section of the seal 30 of FIG. 6 is shown in detail in FIG. 7. The sealing lid 31 is clearly shown as well as the circumferentially parallel outer insertion stop 32.
A modified embodiment of a seal 30 is shown in FIG. 9, wherein the contour of the seal 30 is here produced as a surface seal.
In contrast, FIG. 8 shows a structure with a single sealing cover 31 located on a sealing profile base 31a. Here, the sealing member form base 31a is made as the insertion stop 32, which limits the insertion depth of the insert cartridge in the outlet mechanism in the manufacture of the seal 30 shown in FIGS. 6 and 7.
10 and 11 show two structures of a seal 30 made in the form of a seal member, each having two seal covers 31, the seal covers 31 having a water flow inlet surface of the insert cartridge. It is arranged in the shape of a ring-shaped cylinder in the tip region of. In the seal 30 shown in FIG. 10, the edges of the seal cover 31 have different bevels, in order to influence the deformation at the use position. In Fig. 10, the sealing lids 31 are bent away from each other at the use position of the insertion cartridge due to the beveled edges located opposite to each other, so that a wide end edge area can be sealed. It is effective. Has two sealing lid 31 is shown, each of the sealing lid is provided with an oblique (bevel) on its outer surface, by him 11, bent toward the center of the in-use position of the inserted cartridge, the sealing cover is inserted into the cartridge All.
Fig. 12 shows an advantageous structure of a seal 30, in which a ring-shaped circumferential sealing cover 31 which is effective in turn is provided on the base of the sealing member, which is stepped on each other and has different step heights. Doing. The sealing cover 31 becomes effective in turn as the insertion pressure acting on the insertion cartridge becomes high, where the insertion cartridge is extended and used to maintain the sealing effect for a long time by tightening the insertion cartridge and / or the intermediate holder. Can be. Here, if the highest sealing cover 31 at the outer circumferential edge is already damaged, worn or inflexible to some extent, the next higher sealing cover 31 can achieve a sealing effect again after tightening. Moreover, some irregularities or nonuniformities of counterstops in the outlet mechanism can be counteracted.
Of course, the sealing member form described on the basis of Figs. 7 to 12 can consist of a body, not only on the insert cartridge but also on the intermediate holder, especially at its end edge of the water flow inlet.

The piping function unit shown here can be inserted into the outlet tip of the sanitary drainage reinforcement in such a way that the nozzle that can be screwed from the outer surface to the outlet end can be omitted. Since the nozzle can be omitted in the outlet mechanism shown here, a gap, which will remain between the nozzle and the outlet mechanism, is also omitted if the nozzle is not omitted; The gaps have a detrimental effect on the visual appearance of such outlet mechanisms and serve to hinder sanitary requirements due to the accumulation of dirt. In the outlet mechanisms 1 and 2 shown here, the insertion cartridge is entirely extended in the longitudinal axis and positioned in the liquid guide portion of the outlet mechanism, so that at the same time and at the same time, it is possible that the nozzle or the A uniform coloring or chroming outlet mechanism can be constructed without constructing the components. Since the entire inner diameter of the liquid guide portion provided in the outlet mechanism can be used for the insertion cartridge, a large surface area attachment can also be used, so that the validity period between the two holding intervals is significantly extended. As shown in Fig. 5 , if the insert cartridge having the same structure and intended for exchange is manufactured on the water flow discharge surface in a manner that is screwed, attached and detached, the insert cartridge may also simultaneously function as an assembly and disassembly tool. Can be.
